This means that the space the actual icon image occupies is smaller than the icon pixel size: The recommended border is one twelfth of the icon size. 640 dpi)Įach icon must include a spacing border around the central image, used for on screen spacing and minor image protrusions (such as the bag handle and drop shadow in this example where the border has been indicated in red): 192×192 pixel icon in the res/mipmap-xxxhdpi folder for extra extra extra high density displays (approx.144×144 pixel icon in the res/mipmap-xxhdpi folder for extra extra high density displays (approx.96×96 pixel icon in the res/mipmap-xhdpi folder for extra high density displays (approx.

There is a lot of variation in Android device screen size and resolution therefore screen densities are grouped into ranges: Ideally for sharp images with no pixelation a project will include an icon for all the possible screen densities that an App will encounter. The 48×48 pixel icon is suitable for medium density screens, for all other densities the 48×48 pixel icon is scaled up or down as required. Android supports different screen densities, measured in Dots Per Inch (dpi), which is the same as Pixels Per Inch (PPI) for device displays. The default icon size is 48 by 48 pixels. Android icons are small square Portable Network Graphics (PNG) files. When a project is created in Android Studio default icons are generated in the res/mipmap folders. Inkscape can be used to adjust the images obtained from the Open Clip Art Library before generating resources. This is ideal for generating the different size launcher icons (and other graphical resources) needed for an App. It can be used to generate vector graphic images to a high standard and supports exporting to a bitmap file to any required resolution. Inkscape is a free multi-platform and feature rich graphics program. If you don't want to use an existing image then a graphics program is used to design the launcher icon, and other graphical resources. Every good Android Application (App) deserves a custom launcher icon.
